15 types of pumps and their main characteristics

The types of pumps that exist are intended to improve the quality of life and this is due to their innovations.

These are used very widely, as most industries and household appliances use pumps to pump gases or drive fluids.

Do you want to know the different types of pumps? Then I invite you to continue reading this post where you can learn about all of them in the market.

15 types of pumps and their characteristics

Pumps come in different styles and sizes, each designed for a specific purpose. The types of pumps that exist are:

1. Centrifugal pumps

They are rotating machines where flow and pressure are generated dynamically. Energy changes occur by virtue of two main parts of the pump, the casing and the impeller.

These belong to the types of hydraulic pumps, and the characteristics they present are:

- Impulse in different shapes and sizes according to their performance.
- Its shaft diameter is calculated to minimize deflection in the sealing zone.
- The casing is equipped with a unique suction nozzle and is made of the same materials as the impellers.

Undoubtedly, powerful and multifunctional equipment that is suitable for any industrial application, especially when chosen from Dynex Pumps, a centrifugal pump supplier in the United States that offers quality to its customers.

2. Vertical centrifugal pumps

It is a subcategory of the types of centrifugal pump and is developed for well pumping.

The size of the well bore limits the diameter that is on the outside of the pump controlling the overall pump design.

Its main characteristics are:

- High efficiency.
- Compact structure.
- Easy maintenance.
- High quality materials.

3. Horizontal centrifugal pumps

They are the most commonly used designs in industries. This is due to their design configuration that aligns the pump head in the same plane as the pump motor.

They can be connected with or without coupling, they can be mounted on a base plate if they are coupled in a long or closed way. The characteristics they have are:

- Single suction nozzle.
- Impeller of different sizes.
- Easy maintenance and installation.
- They work in harsh and constant conditions.

4. Submersible pumps

Submersible pumps belong to the category of the types of well pumps, since they are submerged in the fluid to be pumped.

They use a screw mechanism or centrifugal mechanism to drive the fluid. Applications where these pumps are seen are in the agricultural, water and wastewater industries.

The characteristics it has are:

- Easy installation.
- Directly coupled to the motor.
- Quiet operation when submerged.
- The engine is guaranteed to run for a long time.

5. Fire hydrant system

They are pumps used to increase the pressure and flow rate of water required by fire protection systems and which operate simultaneously. Their characteristics are as follows:

- High reliability and high performance.
- Designed for fire pump purposes.
- Manufactured with non-corrosive internal parts to avoid corrosion obstructions.

6. Diaphragm pumps

Other types of pumps found in the industries are diaphragm pumps and are types of positive displacement pumps that use a combination of the reciprocating action of a Teflon, rubber or thermoplastic diaphragm. Notable features include:

- No need for complex controls.
- Unaffected by abrasion and corrosion.
- Handles critical materials safely and reliably.

7. Gear pumps

These types of pumps are also positive displacement pumps that move fluids by engaging the teeth of two gears.

In addition, they are positive displacement rotary pumps used in industrial applications to drive thick liquids such as oils and fuel.

Its characteristics are:

- Self-priming.
- Robust and compact design.
- They work with high viscosity liquids.

8. Peristaltic pumps

They are also known as roller pumps which are used by peristaltic motion to move the fluid by squeezing a tube.

Due to their operational advantages, they are often used in chemical and medical applications, such as reactive chemicals or cardiopulmonary machines that circulate blood.

Main characteristics:

- Gentle pumping action.
- High abrasion resistance.
- Low-cost maintenance.

9. Cam pumps

Also known as rotary lobe pumps, they displace liquids by rotating or through a rotary and orbital movement. The characteristics they possess are:

- Self-priming.
- They handle high viscosity fluids.
- Fixed and pressure independent capacity.

10. Piston pumps

They are also known as plunger pumps and belong to the category of types of vacuum pumps, where a high pressure seal responds by means of a piston.

They are often used for water irrigation, scenarios that require a high and reliable supply system and pressure in order to transport paint, chocolate, pastries, among others.

Its most common characteristics are:

- Vacuum work.
- Handling of vegetables and fruits, slices, fruit cubes, leaves and chunks.
- Pumping of shear-sensitive and particulate products.

11. Electropumps

Electric pumps are types of water pumps that are used to pump water from one place to another and are able to transport dirty water, clean water and various liquids, depending on the domestic or business sector where they are installed.

These types of pumps have the following characteristics:

- They are charged by a battery.
- They are powered by electric motors.
- Body made of stainless steel.

12. Peripheral pump

Also called vortex or regenerative type, it works by swirling the liquid through its blades at very high speeds, producing great force in its impeller.

They are used in both industrial and domestic applications and have these characteristics:

- More economical and perfect for domestic use.
- Ability to handle small quantities of air.
- Its curves present a linear and more pronounced behavior.

13. High pressure pumps

They create the pressure for their operation and supply water to the spraying device. These are used to bring fluids from low pressure to high pressure by means of plungers.

The characteristics of these types of pumps are:

- Reliable performance.
- Perfect for sprinklers.
- They move water effectively over long distances.

14. Pneumatic pumps

Compressed air is responsible for moving the liquid in pneumatic pumps. In pneumatic ejectors, its air displaces the liquid from a pressurized container.

This is fed by gravity through a check valve to the discharge line in a series of surges that depend on a certain time for the tank to refill.

The types of pneumatic pumps have these characteristics:

- Compact design.
- High performance engines.
- Its robust technology guarantees its resistance to dirt.

15. Sludge pumps

This equipment is used to transfer sludge, wastewater and all types of dirty water that may contain particles or solids. Their characteristics are:

- High resistance.
- They are not obstructed.
- Capable of pumping highly viscous solids.

To all this list we can add the types of heat pumps that are considered a source of clean and renewable energy that allows to air-condition a room or house.
